Building Of The Virtual Laboratory On Distance Education Environment

During the teaching of the contemporary information technology, the education of the telenet is very important . In recently the researchers are focusing on how to establish a virtual experiment environment to finish the interactive experiment model. For example constructing the resistance, capacitance apparatus model and the amplifier experiment circuit. The traditional teaching was limited by the economy, time and space , and couldn't satisfy the requirement of all the learner. The VE environment as a computer data model of full three-dimensional information , can use network and interactive video technology transmit to all over the world, so many students can share the teaching resource. With the development of the virtual reality technology, the establishing of the VM will become the facility of virtual teaching.Using the feature of the virtual reality technology tap the virtual experiment segment online education and vividly do many really experiments or finish some problems in traditional education, all these have become the key segment of the contemporary telenet education. Relative to the HTML, virtual reality technology is a multimedia technology, the method of virtual modeling for building different models have the feature of high transfer rate and short data amount, can transmit more informations using the limit bandwidth.VM technology is the core and key to building the VL . In the article offering the model and project of the building the virtual laboratory through the researching the application VM in reality, through IOAC's basic operation experiment improve them feasibility. At the article structure , firstly summarize the VRT' s character, actuality and the evolution ,secondly discuss the feasibility of using VRT doing the experiment online ,thirdly analyze the VE's character, basic function and the key technology of realizing the VE, and then put forward the theory foundation to building the VE above the network, research the empoldering VE project through combining VRML with 3DMAX and JAVA ,and discuss the structure of the VE system and the key technology three-dimensional scene interactive. At last, this thesesis gives the laboratory model of integral operation.
